Cruze 1.4T Tuning?

btw, the same tables used to manipulate fan parameters influence the electronic thermostat. The ECM lets you desire a certain ECT. Do you have HPTuners?

yes i do, i did not know the fan table configured both, my bad. i was just throwin two cents out there

I wouldn't run anything less than 91 octane. I personally run 93 octane here.

These cars are setup from the factory for fuel economy, so you're going to get stupid high AFR, slow PE enrichment, and so forth. Like others, modifying the trans shift times to around .1 makes such a nice difference in the shifts.

I've attached my tune. It is ROUGH, so don't copy it. I'm still trying to understand how things like Pressure Ratio Max work to control boost as I don't think I"m getting full boost where I want it. Seems like until I hit 4k RPM, the boost seems to be held back by something.

Anyone that knows their stuff, feel free to comment on my tune. It's a work in progress.

cool, ill check it out, see what i may have done wrong... my pc crashed sorry for the week late responses.
honestly, i am pretty sure the solid tumbler lip on the intake mani is what is choking the most.. i would like to see how much boost/timing vince runs with his service.

My only concern with that is how it affects the lower RPM power band. I don't see why GM would purposely put a restriction there if it didn't help with making the car more "fun" to drive in the typical powerband.

Sorry, I do not mean the opening/closing of the thermostat is manipulated in that way. I meant more that the ECM seems to let you command a desired ECT. I'll add it to my list of things to observe if I can see when the thermostat is opening in relation to what I desire for coolant temp.

ive been fighting this too lately, i finally have a little time, and i think this obstruction is the problem. it seems like its corked till 4k and finally the boost pushes air past the choke. the choke is for turbulence and mixing fuel for mpg.. gm didnt care about us wanting it fun lol
